SWITCH-STAND.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed February 1, 1908. Serial No. 413,824.

T o all 'whom it mag/ conccrm Be it known that I, EUGENE N. SrnoM, a citizen of the United States, residing at Austin, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Switch-Stands, of which the following is a specification.

The present invention is in the nature of an improvement upon the construction of switch-stand shown and described in Letters Patent of the United States No. 714,060, granted to me November 18, 1902 said construction being adapted for operating the three-throw and other' multiple-throw variety of railway-switch, and involving the use 'of two longitudinally-reciprocable rackbars for connection with the switch to throw it by turning an oscillating shaft with which the bars are engaged through the medium of mutilated pinions.

The primary object of lmy present improvement is to provide a novel construction of the switch-operating mechanism which shall dispense with gears, with the advantages of simplifying the construction and rendering it more durable and easier to operate and enabling the device to be embodied in an ordinary form of upright switch-stand.

Referring to the accompanying drawings,-

Figure 1 is a plan view, partly broken, showing a three-throw railway-switch equipped with my improved switch-stand; Fig. 2, a view in elevation of the switch-stand regarded from the top side of Fig. 1, with the ends of the reciprocating bars broken away; Fig. 3, a view in elevation of the switchstand showing the reciprocating bars by a section taken at the line 3 on Fig. 2 and regarded in the direction of the arrow Fig. 4,'a plan View of the switch-stand on a larger scale than that observed in the representation thereof in Fig. 1; Fig. 5, a section taken at the line 5 on 2 and viewed in the direction of the arrow; Figs. 6, 7 and S are perspective views of the upper reciprocable bar, the bar-actuating head and the lower reciprocable bar, respectively, showing them unassembled but in the relative positions they occupy in the switch-stand; and Fig. 9 is a section taken at the line 0 on Fig. 5 and viewed in the direction of the arrow.

The switch-stand frame represented at 10 is one of an 'ordinai'y type in common use involving legs rising from a base at which it is adapted to be fastened in operative position,

with a table 11 surmounting the frame and containing in its edge the notches 12, 13 and 14 at equal distances apart to receive and rctain the operating lever 15 in its different positions, the lever being fulcrumed at one end on a yoke 16 secured above the table upon the rotatable switch-spindle or targetshaft 17 journaled in a bearing on thc base and passing tlnough a central opening in the table, which is provided with stops 1S and 19 at the ends of the throw of the lever.

Bearings 20, 21 and 22 project horizontally from a corresponding side of each frame-leg near its lower end and each set thereof is covered by a plate 28 bolted to the bearings, which form between them guide-ways for the two horizontally reciprocable bars 24 and 25. The lower bar, 25, contains between its ends a section 26 expanded toward one side of the bar at a transverse recess 27 extending into the bar from its opposite side, with a lip 2S projecting at one side of the recess and a caring-lug 20 provided on the top of the bar -at the opposite side of the recess, where the face of the lug is shown at 30 to be concavely curved, the back of the lug presenting a stopshoulder 31 for the purpose hereinafter eX- plained. The upper bar 24 is the same as the lower bar with its enlargement 82, recess 33, lip 34 and bearing-lug 35 having the concavely-curved face 36 and stop-shoulder 37 arranged correspondingly to their arrangement on the lower bar. The bar 25 is rcciprocably supported in the s'ace between the bearings 21 and 22 and the ar 24 is similarly supported between the bearings 20 and 21, these bars being confined to move on their bearings by the plates 23. The upper bar slides on the top-face of the bearing-lug 29 on the bar 25, and the lower b ar slides against the bottom-face of the bearing-lug 35 depending from the upper bar. On the spindle 17, in the plane between the two reciprocable bars, is secured to turn with it the hub of a head 38, preferably in the form shown of a segment, provided on one end with an upwardly-prejecting stud 39, in the preferred form, as represented, of an anti-friction roller, in position to engage with the recess 33 in the upper bar, and a similar stud 40 depends from the opposite end of the head in position-to engage with the recess 27 in the under bar.

The three-throw railway-switch in connection with which my improved switch-stand '65 recess 27, to the position in which it is repreis shown in Fig. 1 to be operatively applied l sented in Fig. 5. To throw theswitch-rails presents no feature of novelty. 44, 45 the lever is turned toward the notch 14 The divergent stock-rails are represented to the position where it is arrested by the at 41 and 42, the longer point-rails at 43 and i stop 18 (thus toward the right)until the lever 5 44, and the shorter point-rails at 45 and 46. registers with that notch and is dropped into The point-rail 45 is connected in a usual it for locking the switch in the position to manner by a head-rod 47 with the point-rail which it is then thrown by the resultant entry 44, and the point-rail 46 is similarly conof the stud 39 into and its engagement with nected by a head-rod 48 with the point-rail the recess 33 to move the bar 24 and the 43. The point-rail 44 is pivotally connected head-bar 49 correspondingly. through the medium of a switch-rod 49 with stud 40 turns out of the recess 27 and the the adjacent end of the upper bar 24 and the convex edge of the head 38, which conforms point-rail 43 is similarly*connected with the to the concave face 30 of the lug 29, engages adjacent end of the lower bar 25 through the the latter to lock the bar 25 against movemedium of a switch-rod 50. As will therement. At the end of this throw the section fore be understood when with the rails in the 32 coincides vertically with the section 26. relative positions for the main track in which By reversing the throw of the lever to restore they are shown the point-rail 44 is thrown in it to its central position the switch-rails the direction away from the rail 42 into conl 44, 45 are returned to the position in which tact with the point-rail 46, it throws the they are represented in Fig. 1 to re-set them point-rail 45 through the mediumof the headfor the main track and the bars 24 and 25 rod 47 into contact with the point-rail 43, are restored to their initial positions,inwhich and with the rails in the illustrative relative each is in readiness to be engaged by the head positions when the point-rail 43 is thrown in 38 in the manner described for moving it by the direction away from the rail 41 into conturning the operating-lever from its normal tact with the point-rail 45 it throws the pointposition toward the right or left. rail 46 through the medium of the head-rod that l Claim as new and desire to Secure 48 into contact with the point-rail 44. by Letters Patent is- The described throwing of the switch-rails 1. ln a switch-stand, the combination with is produced by turning the operating lever 15 its rotatory Spindle Carrying the Operating as follows: As shown, the lever is depending lever, of a pair of bars each containing a reand confined in the central notch 12 to lock cess and supported on the stand-frame to be the switch with the rails set for the main independently reciprocated longitudinally, track. In that condition of the switchsaid bars being adapted to be connected with stand the bars 24 and 25 occupy the relative point-rails in a railway-switch, and a head on positions in which they are represented in said spindle carrying studs in position to en- Fig. 5 with the studs 39Iand 40 at the open gage a stud with the recess in one or the ends of the recesses 33 and 27, respectively, other of said bars by turning the spindle toand the stop-shoulders 37 and 31 abuttingward the right or left, for the purpose set against the adjacent inner sides of the frameforth. legs, to properly limit the outward movement of the bars. To throw the switch-rails 43, 46 the lever is raised out of the notch 12 to a horizontal position and turned toward the notch 13 until it is arrested by the stop 19, (thus toward the left) to rotate the spindle 17 and head 38 through an arc of ninety degrees until the lever registers with that notch and is dropped into it for locking the switch in the position to which it is thrown by the resultant entry of the stud 40 into and its engagement with the recess 27 to move the bar 25 and head-rod 50 correspondingly. Meantime the stud 39 turns out of the recess 33 and the convex edge of the head 38, which conforms to the concave face of the lug 35, engages the latter to lock the i bar 24 against movement. At the end of this throw the section 26 coincides vertically with the section 32. By turning the lever back to the central notch 12 the rails 43 and 46 are thrown to their initial positions, and the bar 25 is thereby returned, under the reverse engagement of the stud 40 with the its rotatory spindle carrying the operatinglever, of a pair of bars, each containing a recess and supported one above the other on the stand-frame to be independently reciprocated longitudinally, said bars being adapted to be connected with point-rails in a railwayswitch, and a head on said spindle carrying an upwardly projecting and a depending stud in position to engage, respectively, with the recess in the upper bar and that in the lower bar by turning the spindle in opposite directions, for the purpose set forth.
